For the fifth straight year, the National Auto Auction Association reported growth in sales of used vehicles in both unit terms and dollars transacted in 2016.
NAAA said Tuesday its 20th annual survey, conducted by CliftonLarsonAllen of Arlington, Va., found that sales of used vehicles — the sum of actual and estimated vehicle sales — by the association's member auctions rose 4.6 percent to 9.8 million units in 2016, up from 9.3 million units in 2015.
The gross value of vehicles sold rose to $100 billion, setting a record at NAAA member auctions for the second straight year, the survey found. Sales totaled $90.6 billion in 2015, which broke the record set in 2007.
NAAA also said the survey revealed the number of vehicles entering auctions grew 2.3 percent to 17.7 million.
Of those 17.7 million vehicles:
• 52 percent were dealer consignment vehicles, down from 57.1 percent in 2015
• 40.3 percent were finance and fleet vehicles, including off-lease, fleet and repossessions, up from 35.1 percent
• 6.5 percent were sold by automakers, down from 6.9 percent
• 1.2 percent were from other sources, up from 0.9 percent in 2015.
